Question

Trowel Size For Thin Glass Mosaics?


Ok, guys, the lady of the HO decided to do powder room wall with paper thin glass tiles, like size 3/4"x 3/4" in mesh.
I probably use Glass Tile Adhesive by Laticrete, but I am not sure what size trowel I should use,1/8"/ 3/16 notched as Laticrete says, any tricks? I've done thicker glass mosaics but never this thin.
Should I trowel the thinset, then flatten it, then set? I can flatten the thin set pretty even if I need to.

Sam,

I like the Mapei glass adhesive better. More open time, I think. The trowel I use is 3/16x3/16 square notch. In a wet area, I burned in a skimcoat first and let it dry. The next day, I troweled the thinset and flattened the trowel ridges. Be sure to have a line of thinset along the trowel edge that you flatten the ridges with. Set the tiles and push into the thinset with your float. A glass mosaic nipper is a must IMO. Have a brush to clean the grout joints of any wet thinset. You don't want to risk chipping the glass tile with a razor knife after the thinset dries.

Re: Trowel Size For Thin Glass Mosaics?


For the really thin glass, I like to use a Kerdi Trowel first. Pull off the first sheet and check coverage to make sure...then if need be I go to the worn down 3/16" Vnotch.

No need to knock down the ridges, unless the glass is totally transparent. Some of those glass tiles I have used were opaque.

Is the tile paper face or mesh mount?

The float idea is what I always do too.

That kerdi towel might be better. The smaller notch might not make tall enough ridges to be knocked down but check. Some glass, even with backing, can reflect the ridges between the tiles if the ridges aren't knocked down.

Re: Trowel Size For Thin Glass Mosaics?


Thanks to y'all. I appreciate all your input. The glass tiles are actually 1/2" x 1/2"and mesh mount and thin as dime,
Since the wall is 9' over the sink cabinet and 42" wide, I decided to go with Bonderatile mat.
I like new innovations and this product looks like work me. It will save time and effort, kind of expensive $4 per sq.ft.
I will take pics and post it here.

Re: Trowel Size For Thin Glass Mosaics?


Update:
I totally forgot about this..
This was a 42" wide and 106" high powder room wall. As I mentioned before I purchased Bondera tile mat, it comes in 12" wide and 10' long.
Basically it is a double sided tape-in large format.
Attached to the wall easily,need to be careful as you set, this is one sticky piece.
I have used laser guide and attached the mosaics and Rontec trim at for edges. Limited access in a tight space was the main problem setting it with thin sets,this way,after 5' done from the bottom, I just laid a lather against to reach high.
Finished with charcoal grout.
Overall, much faster (all in a day)than thin sets,no mess,push as much as you wish to mosaics..
